• Abstract:
  This letter report presents an updated implementation for thrust reversers in AEDT. Currently, thrust reverser is applied to all STANDARD approach profiles in the Integrated Noise Mode (lNM) as 60% of the max rated thrust for jets and 40% for props over a distance of 90% of the total roll-out distance after touchdown. These thrust values during landing ground roll in INM were used to ensure good agreement between measured and modeled noise, but were not necessarily representative of actual thrust levels during thrust reverser deployment. The ground roll distance associated with reverse thrust in INM is also somewhat arbitrary. Since the aircraft performance model is common to noise and emissions computations in AEDT, the unrealistically high thrust assumption specifically is an issue when computing fuel flow and emissions. Therefore, there is a need to update thrust reverser assumptions in AEDT to better represent conditions in typical aircraft operations.
